what does this have to do with the whiteness of clouds?

Question

tiny particles, like tiny bells, scatter high-frequency waves more than low-frequency waves. Large particles, like large bells, mostly scatter low frequencies. Intermediate-size particles and bells mostly scatter intermediate frequencies. what does this have to do with the whiteness of clouds?

Answer 1

The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. White light is a mixture of all the colors of the visible spectrum. Black is a total absence of light.
Maybe:
The moisture drops in the clouds must be of all different sizes
and scatter light of all frequencies, which would be seen as white?

Answer 2

gaitorbaiter's answer is correct. Clouds consist of many, many water droplets over a range of sizes. Light entering a cloud is scattered by them, and because the droplets are of many sizes, all wavelengths of light get scattered on all directions. Whote comes out is a uniform mixture of scattered light at all wavelengths, which of course is white.

You get the same effect with ground glass. Although glass itself is transparent (like a window), when you grind it up or pulverize it it looks like a white powder.

Answer 3

In order for clouds to be white, they have to reflect all white light, which is all the color frequencies. The particles in the cloud allow all these light waves in the visible spectrum to be reflected into our eyes.

Answer 4

Scattering i.e. reflection of light by particles whose size is equal to or smaller than wavelength of light obeys RAYLEIGH"S law which states that percentage of light scattered is inversely proportional to FOURTH POWER of wavelength i.e. in the visible spectrum, BLUE IS SCATTERED MORE

Particles in the sky are of sizes smaller than 600 nano meter hence they scatter BLUE and hence SKY appears BLUE.

But size of particles in clouds (also salt , sugar) is much larger than wavelength of visible light hence the Rayleigh law is not obeyed and all colors are scattered , hence CLOUDS (salt, sugar) appear WHITE

Answer 5

A thing is NOT white if it absorbs some frequencies. Water does not absorb visible frequencies.
